FIRE-POT FOR STOVES.

SPECIFICATION forming part of Letters Patent No. 661,258, dated.November 6, 1900.

Application filed January 19, 1900. Serial No. 1,969. lNo model.)

' Michigan, have in vented certain new and useful ImprovementsinFire-Pots forStoves; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in fire-pots for stoves, and moreparticularly to improvements in firepots for stoves having plaincylindrical sheet-metal bodies; and the objects of my invention are toprovide improved means for supporting the fire-pot within the stove andfor securing the same in place therein and to provide the device withcertain new and useful features hereinafter more fully described, andparticularly pointed out in the claims. Y

My invention consists, essentially, in providing a ring having aninwardly-projecting and upwardly-inclined flange, securing the ring tothe inside surface of the cylindrical body of the stove, providing thefire-pot with an outwardly and downwardly projecting flange to engagethe ring, and securing the fire-pot in place by means of bolts extendingthrough this flange and down through the base of the stove, whereby thefire-pot is securely held in place and the body of the stove alsosecured to the base.

It consists in further providing an air-chainher at the top of thefire-pot consisting of a flaring concavo-convex ring resting upon thetop of the fire-pot at its lower side and engaging the inner surface ofthe body of the stove at its upper side and held down upon the fire-potby means of said bolts, as hereinafter more fully described, referencebeing had to the accompanying drawings, in which Figure 1 is a verticalsection of the device embodying my invention, taken on the line 1 1 ofFig. 2; Fig. 2, a plan view of the same, and Figs. 3 and 4 detailsshowing the potsupporting ring detached.

Like letters refer to like parts in all of the figures.

A represents the body of the stove, having an inwardly-pressed head Aopposite the fire-pot.

B is the fire-pot, provided near the top with an outwardly anddownwardly projecting flange B and also having a series of openings H inits upper edge.

0 is the base of the stove, upon which the body A is supported andhaving an inwardly extending flange surrounding and engaging thefire-pot near the bottom thereof.

D is the pot-supporting ring, made in segments for convenience ininserting the same within the body of the stove and also to provide forunequal expansion of the various parts, and having an inwardly andupwardly projecting flange G at the top to engage the flange of thefire-pot and support the same and an annular groove F in its outersurface to engage the bead A in the body of the stove and secured inplace by suitable rivets or bolts.

K is the air-chamber, consisting of an outwardly and upwardly flaredconcavo-convex ring adapted to rest upon the top of the firepot at itslower side and engage the inner surface of the body of the stove at itsupper side and provided with suitable bosses J, through which the boltsI extend vertically through the flange B and the inwardly-projectingflange of the base 0.

E E are pipes inserted in the air-chamber K for the purpose of conveyingair to the same from any convenient source.

The ring D is made in any convenient numberof segments, and one or moreof the seams where the segments join extend diagonally across the ring,as shown at D, to enable the last segment to be properly inserted inplace when the inwardly-pressed head A and the groove F are utilized.These latter, however, may be omitted and the rivets or bolts reliedupon to hold the ring with quite satisfactory results; but I prefer theconstruction as herein shown. By placing suitable cement between thering D and the body A an air-tight joint is formed, and the flange Bbeing movable upon the ring D any unequal expansion of the parts willnot strain the stove or bolts I. Said bolts also being located whollyoutside the fire-pot, they will not be exposed to the action of thefire. Any dust or ashes accumulating in the angle between the ring D andthe body of the stove will also tend to prevent any leakage of airbetween the same.

Ithus secure a very effective and durable support for the fire-pot,especially adapted to be attached to a sheet-iron stove and also forminga portion of an airchamber surrounding the top of the fire-pot fordistributing air to the fire.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. In a stove the combination of a ring having an inwardly and upwardlyprojecting flange, a fire-pot having an outwardly and downwardlyprojecting flange engaging the flange on the ring, a continuoussheet-metal body extending above and below the ring, and means forsecuring the ring to the inner surface of the body, substantially asdescribed.

2. lhe combination of a sheet-metal body having an inwardly-pressedbead, a ring secured to the body and having one or more diagonal seams Dand a concave channel opposite the bead, and also having aninwardlyprojecting flange, and a fire-pot having an outwardly-projectingflange to engage the flange on the ring and supporting the fire-pot,substantially as described.

3. The combination of a sheet'metal body having an inwardly-pressedhead, a ring secured to the body and having a concave channel oppositethe bead and an inwardly and upwardly projecting flange; and a fire-pothaving an outwardly and downwardly projecting flange engaging the flangeon the ring and slid-able thereon, substantially as described.

In testimony whereof I affiX my signature in presence of two witnesses.

PETER J. UOPPENS.
